Summary

The da Vinci robotic system was developed to improve both operative maneuverability (through multi-articulated instruments) and the surgical view (via a three-dimensional camera). Although the system has many advantages, skin incision, wide flap dissection, and pneumatic/mechanical retraction remain essential, but cause postoperative pain and slower recovery. Previous studies found that pectoralis fascial blocks were easy to establish; local anesthetics are injected between two adjacent myofascial layers under ultrasound guidance, providing the surgeon with a clear image. Analgesic efficacy has been validated during robotic thyroidectomy in our institution. The pain outcomes were comparable between the groups, but there were fewer complications in the PECS II group. The investigators investigated whether this block can reduce postoperative pain during wide flap dissection for single-port robot-assisted transaxillary thyroidectomy.

Type	Name	Description
PROCEDURE	Pectoral nerve block	An ultrasound probe was placed obliquely over the second and third ribs below the lateral one-third of the clavicle. After identification of the anatomical structures, the needle was advanced along a superior-medial-to-inferior-lateral passage to the tissue plane between the pectoralis minor and serratus anterior muscles, and 20 mL ropivacaine (0.375% w/v) was injected at the level of the third rib. The anesthetic spread around the axilla, and the needle was withdrawn to the point in the plane between the pectoralis major and minor muscles. A second injection of 20 mL ropivacaine (0.375% w/v) was then delivered (PECS II).
